A. Nacer@ "restarted` To all whomvzt may concern:

Be it known that I, LEWIs A. NUCERA, a

'citizen of the United States, residing at Buffalo, in the kcounty ofuErie and State of New York, have invented certain new and useful Improvements in Resilient -Wheels;

l and I do hereby declare the following to be invention is. to provide a wheel having an improved hub construction withwhich'the spokes will be connected and which will include an improved spring construction yieldably holding the spoker carrying rim spacedvfromthe hub proper andv permittingthis spoke carrying rim to have necessary movement to take up shocks received when passing over rough roads.Y Another object of the invention'is to so construct the wheel that the spring construction thereof will be very strong and durable and not liable to easily break or-move out of the properl position. Anothercbject of this invention is to so construct the hub portion of the wheel that the spring construction thereof will be inclosed and the springs thus preserved against exposure to weather and injury from dirt and mud and to further so construct this hub that it may bee'asily assembled or taken apart when necessary for` cleaning or repairing.

This invention is illustratedin the Aaccompanying drawings wherein: A

` Figure 1 is a sideelevation of the improved Wheel, Y

Fig. 2 is a view showing the improved wheel in vertical section,

Fig. 3 is a transverse sectional viewr through the wheel,

Fig. 4 is a transverse sectional view through the hub portion of the wheel disclosingl a sliggghtlyY modied construction.

This wheel is provided with a hub having side plates 10 and 11 which are extended parallel in spaced relation and are heldin spaced relation by circular webs 12and 13 which extend from the side plate 10, as shown in Fig. 3, and are connected at points about the circumference of the hub structure by the radial ribs 14 and 15. At the junction of the radial ribs and circular web 13 there has beenprovided threaded open- S'peciica'tcn of Letters Patent.l

ings 15a which receive the screws 16. These screws 16, together with the screws 17 which fit into vsockets 18 inthe annular web 12, serve to releasably hold theside plates 11 in place thus permitting the removal of the side plates 11 when it is desired to have ac` cess to the interior of the hub structure.

T he inner spoke carrying rimis of a channel construction and is provided with side walls 19 and 2O connected by an annular web 21 upon which. the inner ends of the spokes 22 will rest. These spokes 22 are provided with enlarged heads at their inner ends which contact and completely fill the spoke carrying rim thereby preventing circumferential movement Aof the spokes Y when the spokes are in place and secured by the bolts or other fasteners 23. These spokes extend outwardly in radiatingrelation from the hub and have their outer ends suitably `connected with thefelly or 4rim 24Cy upon `which the tire willfbe placed. As'the reency there has rbeen provided within the hub Vand between the web 13 and the web 21 ofl the spoke carrying'rimzcircularj springs 25 which are positioned as clearly shown in F ig'. 2 and secured by rivetsV orl other fas-v tenersfto the webs 13 and 21. These springs a 25fare bracedy interiorly lby spiral springs 26 which extend diametrically of the springs 25 and radially of the wheel and thus serve to greatly strengthen the springs and permit them to absorb heavy shocks in going over rough roads without danger o the springs 25 being broken. From an inspection of Figs. 3 and 11 it will be readily seen that each of these springs 25 may be provide-d either with one spring 26 or with a plurality of these springs according to the size ofthe wheel and type of car upon which the wheel is tobe used. Spiral springs 27 are positioned between the springs 25 and are Vprovided with terminal blocks 28 engaging the springs 25 and conforming to the contour thereof thus preventing the springs 27 from being bent and twisted' out of shape when the wheel is in use. These n springs cooperate with the springs 25 and 26 in taking up shocks received in goingA over rough roads and further serve to brace the springs 25 and give them greater resiliency. In order to protect the inner splge carrying rim and the inner faces of the side plates 10 and l1 from undue wear when the wheel is in use, there have been provided bushings 29 and 30 which are secured to the spoke carrying rims and hub plates, respectively, and can be easily removed and renewed when necessary. Therefore, the bushings will receive the wear instead of the spoke rim and hub plate and it will not be necessary to renew the hub plate or spoke carrying rim in order to eliminate side play oi the spoke carrying` rim. These springs should be protected from exposure to weather as much as possible and in order to accomplish this object and not only keep snow and water out of the hub as much as possible but also to prevent mud from` adhering to the bushings 29 there have been provided annular plates 3l which are secured to the hub plates and extend between the inner and outer plates 32 and 33 secured to the side walls of the spoke rims. These inner and outer plates 32 and 33 will be held in spaced relation by spacers 34: and therefore the plates 31 may have free movement between the plates 32 and 33. As previously stated, these platesserve as battles covering the overlapping portions of the spoke carrying rimsand side plates of the hub thus preventing mud and snow from accumulating upon this portion of the wheel.

This wheel will be assembled as clearly shown in Figs. 2 and 3 of the drawings and when in use will provide a resilient wheel iny which the springs 25, 26 and 27 will effectivelytake up all shocks received in going over rough roads. The springs will co- ,operatein taking up the shocks and .the

springs 26 and 27 will serve to prevent the springs 25 from being bent out of the desired shape. `When it 1s desired to make any` necessary repairs to the hub or to clean and lubricate the saine, this can beleasily done by removing the ba'He plate at one` side of the hub andthen remove the screws 16 and 17 thus releasing the side wall l1 of the hub. The interior of the hub will then be exposed to view and any necessarywork can be easily done. I have thusprovided a wheelwhichjwill be very strong and durable and simple in construction and operation. w f

What is claimed is:

. l; A resilient whee-l comprising a hub structure having side plates, annular webs extending from one of the side plates .to the second plate to hold the plates in spaced relation, radiating webs extending between the annular webs, means releasably connectingthe second side plate with the annular webs, a spoke carrying` `rim positioned be tween the side plates of the Yhub structure and having side walls and an annular web connecting said walls, and springs positioned between the annular web of the spoke carrying rim and one of the annular webs of the hub structure and connected theremain springs being connectedwith said an` nular web of the rim and with the hub structure, the side platesof the rim being positioned outwardly of and working over said side plates of the hub structure, reinforcing springs secured in the circular springs and extended radially of thewheel, and circumferentially extended reinforciner springs connecting the circular springs and extended between the latter.

In testimony whereof I aix my signature in presence of two witnesses.
